在 MATLAB Online 中打开

   function y = delay(x)
       persistent n z
       [ L, M ] = size(x);
       if isempty(z)
           n = ...
           z = zeros(n,M);
       end
       if L == n
           y = z;
           z = x;
       else
           if L > n
               y = [ z ; x(1:L-n,:) ];
               z = x(L-n+1:L,:);
           else
               y = z(1:L,:);
               z = [ z(L+1:n,:) ; x ];
           end
       end
   end
